The role of endoscopy in bariatric surgery.

Morbid obesity is a chronic disease of excess fat storage, characterised by premature death and obesity-associated co-morbidities.

Gastrointestinal complaints and digestive complications may, however, increase and may require an actively involved gastroenterologist.
